Slim or HAML Themes

Any ideas on how Haml or Slim could be integrated into the SilverStripe theme development environment? After using Haml and now Slim for quite some time, it really is burdensome to even consider using a more traditional template development that SilverStripe offers.

For example, this project, wordless, integrates Haml, CoffeeScript and Compass into the workflow and is a fantastic method for WordPress theme dev.
